More often than not, the emphasis is laid on the essence of employing organic manures for raising plant seedlings and even in improving the nutrient status of their growth media for higher productivity. Afrormosia elata has numerous medicinal uses but not very much available. Thus, the study on the effects of fish pond sediments (FPS) and decomposed cow dung (DCD) on the early growth of A. elata seedlings was carried out at the nursery ‘A’ of the Federal College of Forestry, Ibadan, Nigeria. A. elata seeds were sown in a finely perforated sieve (filled with washed river sand) and seedlings were pricked – out 2 weeks after seedling emergence into polythene pots with varying levels of FPS and DCD. The experimental design was Completely Randomized Design (CRD) consisting of nine treatments and eight replicates. Treatments include; T1(2 kg of FPS + 2 kg of topsoil); T2 (2 kg of DCD + 2 kg of topsoil); T3 (1.5 kg of FPS + 2 kg of topsoil); T4 (1.5 kg of DCD + 2 kg of topsoil); T5 (1 kg of FPS + 2 kg of topsoil); T6 (1 kg of DCD + 2 kg of topsoil); T7 (500 g of FPS + 2 kg of topsoil); T8 (500 g of DCD + 2 kg topsoil); and 2 kg of topsoil without any treatment served as control). Morphological parameters such as seedling height, collar diameter and leaf count as well as leaf biomass were assessed and the data collected were subjected to Analysis of Variance (ANOVA). The result showed that T3 (1.5 kg FPS + 2 Kg TS) had the best performance in height, leaf area and leaf biomass with mean values of 11.02 cm, 21.65 cm2 and 1.16 g respectively. Though, there were no significant differences amongst the growth parameters assessed for this study. But T3 (1.5 kg FPS + 2 Kg TS) could be employed in raising the seedlings of this plant for faster growth rate.

This study was conducted in order to estimate growth and volume production of Teak (Tectona grandis) in Kanya Forest Plantation, Nigeria. The plantation was divided in to six strata-based age classes (A=38, B=37, C=36, D=35, E=34, F=28, years). Five plots were randomly selected from each stratum. Trees within each plot were enumerated and measured. Variables measured include total height, diameter at the base, middle, top, and diameter at the breast height were taken from 30 temporary sampled plots of 25x25 m approximately from the center, 180 dominant trees were selected from 712 trees. Descriptive statistic was used to summarize the results while inferential statistic (correlation) was used to establish relationship growth and yield variables. Basal area and volume of sampled trees were computed using Excel as well as scatter plots, correlation analysis was achieved using SPSS statistical package version 20. The results of growth and yield values obtained from the dominant trees are (B=249.312 m3/ha, D=196.128 m3/ha, F=134.976 m3/ha, C=119.328 m3/ha, E=100.320 m3/ ha and A=86.976 m3/ha). The results showed that B was (37 years) the best and A (38 years) was the poorest. The results of correlation showed positive relationships with most of the tree growth and yield characteristics but negative relationships exist between age and some parameters that is to say as the age increases those parameters are decreasing.

The paucity of information on chainsaw milling enterprise has contributed to poor planning and development of timber resources in Nigeria. This study has accessed the marketing efficiency and structure with a view of evaluating its potential contribution to the livelihoods and economic development of Benue State. Multistage sampling technique and purposeful sampling technique were applied to determine the study sample which was drawn from the three geopolitical zones in the State; Zone A, Zone B and Zone C. Applying a sampling intensity of 30%, seven (7) Local Government Areas (LGAs) were sampled from the 23 LGAs of the State for the study.  Based on this arrangement 79 chainsaw millers were selected and interviewed on the trading activities. Data were collected and analyzed using descriptive statistics such as percentages and frequency distribution. Also gross margin analysis, marketing margin, marketing efficiency, Analysis of variance, T-test Statistics, Index of market concentration (IMC), Rate of return on investment (RORI) and Gross Ratio (GR) were used in the determining the profitability and the efficiency of chainsaw millers trading efficiency in the study area.  The study revealed that the trade is male dominated having 100% of the respondents as males. Similarly, the indigenous groups dominated the chainsaw milling and with the Tiv having the majority of (65.8%), this was followed by the Idoma (13.7%), Igede, (12.5%) and Igbo (5.5%), Igala and Sura 1.4% each. The study identified 18 timber species that were marketed in the study area and that 2,411, 37,733, and 69,492 volumes were marketed in zones A, B and C respectively.  The result of the gross margin and market efficiency showed that that the chainsaw milling activities are profitable and efficient.  It revealed the mean monthly gross margin (GM) of 39,688.00, 128,730, and 84,000 with corresponding RORI of 84.19, 43.93, and 1.80 for the chainsaw millers. The Analysis of Variance (ANOVA) of GMs were significant with 0.013. The Total Revenue and Total Variable Cost (TVC) equally showed significance with 0.045, 0.000, 0.000. The IMC, Gini coefficient of 0.1891, 0.3218 and 0.1829, indicated that the concentration was low with income inequality but with a competitive market.

Cassava has gained prominence in the world and has become economic crop in the Nigerian agricultural sector. Secondary data was used for this study. The required variables were extracted from General Household Survey Panel Data (GHS-P). The GHS-P is a nationally representative survey of households across Nigeria covering urban and rural sectors. Analytical tools used included Total factor productivity and Markov chain. 82% of populations of Cassava farmers are in the rural areas and close to 73% were young adults including both male and female involved in cassava production. Approximately 65% of the cassava based farmers were single that not yet married and most of the farmers were educated and about 80% and 98% of the cassava based farmers did not have access to credit facilities and extension personnel respectively. Generally, the cassava productivity growth was erratic and very small proportion of cassava farmers that were in lower productivity reduced overtime, while the minimal proportion of cassava farmers that moved into both moderate and high productivity increased overtime respectively.  Generally, there is more to be done to increase and attain sustainable high level cassava productivity growth in Nigeria.

Forest is one of the main sources of different resources where indigenous communities are mostly dependent on the forest for their sustainable management of life. Following the dependency of indigenous communities on natural resources and their conservation practices and development of Village Common Forest (VCF) in Chittagong hill tracts. Present study was conducted at Haduk Para and Hridoy Member Para VCF’s in Khagrachari, Bangladesh to understand the dependency and practices of villagers on the VCF for their livelihood and other resources. Among different types of products extracted from Haduk Para and Hridoy Member Para, the monetary value was highest (14700 BDT and 22400 BDT, respectively) for timber but fuelwood is the most extracted product (1930 Kg HH-1Yr-1 and 2470 Kg HH-1Yr-1, respectively) they have collected from VCF. Besides, to fulfill daily personal needs different plant edible products, fauna, and medicinal plants have been collected by the community people from both VCFs. In case of conservation purpose, Hridoy Member Para giving more priority for protecting the source of water resources where the majority from Haduk Para community replied that their priority was to avert natural calamities. However, both the VCFs community have taken some initiatives to reduce the pressure from the forest floor like enrichment planting, non-wood forest products cultivation, regional training for handicraft manufacturing and alternative income generation activities for the villagers. Therefore, safeguarding forest and biodiversity resources and at the same time improving the livelihood security for the indigenous communities, nowadays is mandatory to protect and manage these VCFs from being degraded.
